A 61-year-old woman with swine flu has died in NSW, raising the number of deaths in the state to four.
The woman, who had underlying medical conditions, died at Lismore Base Hospital on Saturday.
Subsequent tests revealed she had the H1N1 virus, a NSW Health spokesperson said.
Two other men with suspected swine flu died overnight at Royal North Shore Hospital, however tests are still being undertaken to determine if they had the virus.
Swine flu facts: the virus, the symptoms, the treatment"These are two unrelated men, aged in their 30s and 40s, who were being treated for other conditions in intensive care," NSW Health said in a statement.
"These two patients have been referred to the coroner."
The Lismore death follows that of a 27-year-old man on July 4.
He was reported to have been suffering multiple "underlying medical conditions" along with swine flu and died at John Hunter Hospital at Newcastle.
One day earlier a 57-year old was diagnosed with the virus and died the same day at Westmead Hospital in Sydney's west.
A 45-year-old man was the first person to die after testing positive to the swine flu.
Since the epidemic began in NSW, some 346 people have been admitted to hospital, with 50 of these requiring admissions to intensive care units, NSW Health said.
In Australia, 21 people with confirmed swine flu have died, with 2,029 people testing positive to the virus in NSW.
